An image forming apparatus is provided to solve a problem that a space part is formed between papers so that a smaller amount of papers is piled on a pile deliver unit if the papers are irregularly piled. An image forming apparatus includes a body, a detection unit(100), a paper arrangement unit(200), and a controller(300). The body has a pile delivery unit(10). The detection unit(100) determines if a paper is discharged. The paper arrangement unit(200) pressurizes the top surface of a paper discharged through the pile delivery unit(10) and arranges the paper by being stuck to the paper onto the pile delivery unit(10). The controller(300) controls the paper arrangement unit according to the output signal of the detection unit(100). The paper arrangement unit(200) includes a driving source, a rotation shaft, and a lever member. The driving source operates according to the output signal of the detection unit(100). The rotation shaft is coupled to the driving source. The lever member is fixed to the rotation shaft to rotate at an angle of 360 degrees according to the rotation of the rotation shaft.
